Abstract: PURPOSE:To enhance fuel consumption by determining shift-up and shift-down speed changing curves on the basis of a turbine rotational speed v.s. engine load characteristic curves along which an engine may be driven at a high heat-efficiency. CONSTITUTION:Output signals from a turbine rotational speed sensor (b) and an engine load sensor (g) are compared with a shift-down speed changing curve Ld that is set, on the low speed side, corresponding to one-half of a range (alpha+alpha) of variations in the output shaft rotational speed of a torque converter (a), which range is calculated in accordance with the difference between gear ratios of adjacent speed shift stages with respect to a turbine rotational speed v.s. engine load characteristic curve A along which an engine may be driven at a high heat efficiency, and a shift-up speed changing curve Lu which is similarly set on the high speed side. Therefore, whether shift-down or shift-up is necessary or not is determined. When judgement is made that it is necessary, a shift-down discriminating means (h) or a shift-up discriminating (i) delivers a shift-down instruction signal or shift-up instruction signal.

Filed: 1979-07-31
Abstract: PURPOSE: To increase a heat collecting effect by penetrating a heat transmission tube through the header of vessel, as well as sealing the liquid to evaporate in a header pipe and a branch pipe.  
     CONSTITUTION: A heat transmission tube 3 is penetrated through the header pipe 1 of the vessel 18, sealing the fluid which evaporates in the header pipe 1 and the branch pipe 2. The fluid sealed within the header pipe 1 and the branch pipe 2 is evaporated by the solar heat collected by each branch pipe 2, causing the gas to heat the water which circulates through the heat transmission tube 3. The hot water heated by the heat transmission tube 3 is reserved in the regeneratot 21 connected with a pump 13. This enables the gas evaporated by the branch pipe 2 to contact with the heat transmission tube 3, causing to increase the thermal transfer amount corresponding to the water contained in the heat transmission tube 3, resulting to increase the heat collecting effect as a result of obtaining the high temperature water.

Title: Traveling equipment for unmanned carrier
Inventor: NISHIBE KUNIHIKO
IPC: G05D1/02
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of erroneous detection by an address detection sensor and to accurately perform guiding traveling without the generation of an opposite magnetic field around a crossing part by forming elimination parts near an intersection excluding the intersection of magnetic guiding bodies positioned at the crossing part of traveling paths. SOLUTION: A floor block 10 is laid at the crossing point 4 of the traveling paths and two linear magnetic guiding bodies 20 are perpendicularly disposed on the surface. In this case, the elimination parts 22 are formed near the intersection 21 excluding the intersection 21 of the magnetic guiding bodies 20. The clearance of the elimination part 22 is set so as not to generate the magnetic field opposite to the magnetic field of the intersection 21 of the magnetic guiding bodies 20 around the crossing part or branching part of the magnetic guiding bodies 20. Then, at the time of straight traveling, an unmanned carrier 1 travels straight as it is while detecting the magnetic guiding bodies 20 and 21 by guiding sensors 41 and 42.  Even though a section without the magnetic guiding body, that is the elimination part 22, is present in the middle, since the section is extremely short, traveling is performed without disturbance.

IPC: F02M51/08
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injector which stably keeps an air-fuel ratio for a model engine used under severe conditions and has excellent responsiveness. SOLUTION: A magnetic core 32 is inserted into a solenoid coil 32 in an equipment body 31. A fuel-feed passage 35 is in the magnetic core 34. A movable valve element 38 which is magnetically attracted by the magnetic core 34 is in the coil 32 in the equipment body 31. The valve element 38 has a flow passage 39 communicating with the feed passage 35. The valve element 38 is urged by a flat spring 44 to be brought into contact with a valve cage 36, to close a fuel injection port 37. Used fuel is pressurized at low pressures of 20 to 100kPa which are equal to the pressure in the crankcase in a model engine. The moving direction of the valve element 38 in a fuel injector 30 is made parallel to the traveling direction of a model plane, and the fuel injection port 37 of the fuel injector 30 is made to be directed forward in the traveling direction of the model plane.  At rapid acceleration of the engine, the movement of the valve element 38 in its attracted direction by the magnetic core 34 is urged by the movement of the model plane itself. As a result of which, excellent responsiveness is obtained and the amount of fuel supplied rapidly increases. Even at deceleration, the same effects can be obtained.

Abstract: PURPOSE: To provide a high speed differential driver which can really generate the complementary differential output by preparing such a constitution where the transfer gates which are complementary to each other produce the accurately complementary voltage signals at the input terminals of an amplifier and are controlled by the same logical input signal. CONSTITUTION: A transfer gate 31 includes a pair of FET devices 35 and 37 which are controlled by a logical input signal (e) and the inverse of signal (e) which are almost complementary to each other. A transfer gate 33 has a pair of FET devices 43 and 45 having the same structures as the devices 35 and 37. The device 43 has a low voltage terminal L which is connected to the input terminal B of an amplifier and is controlled by the signal (e) at a gate 47.

Therefore, the pass gates which are controlled by the same signal (e) can secure the accurately complementary voltage levels that are applied to the input terminals A and B of a differential amplifier even though the signals (e) are not accurately complementary to each other.  Accordingly, the output signals of output terminals C and D of the amplifier are also accurately complementary to each other.
